What is fuel crossfeed and when would you use it on the A320?

• A. Crossfeed transfers fuel between tanks to balance center of gravity or meet engine-out fuel requirements; used for balancing or fuel management.
• B. Crossfeed transfers fuel between tanks to increase fuel consumption.
• C. Crossfeed transfers fuel from wings to tail.
• D. Crossfeed is a procedure to check fuel quantity.

Answer: (A)

Fuel crossfeed on the A320 lets you connect the left and right wing fuel systems so fuel can be moved between tanks. This is used to balance the aircraft's weight distribution as fuel is burned and to ensure an engine can be fed adequately in an engine-out situation. By transferring fuel from one wing to the other, you can meet center of gravity limits and maintain safe engine operation when one engine needs support or when balancing is required.

This is why the statement describing crossfeed as transferring fuel between tanks to balance the center of gravity or meet engine-out fuel requirements, and being used for balancing or fuel management, is the correct interpretation. It’s not about increasing overall fuel consumption, moving fuel to the tail, or simply checking fuel quantity.
